People who carefully and painstakingly prepare for mass extinction don't exactly seem like the type of people who plan great parties. At least, with those vast collections of guns, ammo, and other terrifying armaments, I certainly hope not. Then again, I suppose everyone will need a drink or 10 to get through the inevitable horrors of forever navigating the "what's for dinner" question without Seamless or, you know, realizing that your urban-dwelling family members will probably never arise from the blasted pit of rubble where their apartments once stood.
This group has a primary concern with maintaining some form of legal system and social cohesion after a breakdown in the technical infrastructure of society. They are interested in works like The Postman by David Brin,[46] Lewis Dartnell's The Knowledge: How to Rebuild Our World from Scratch,[47] or Marcus B. Hatfield's The American Common Law: The Customary Law of the American Nation.[48]
One newsletter deemed by some to be one of the most important on survivalism and survivalist retreats in the 1970s was the Personal Survival ("P.S.") Letter (circa 1977–1982). Published by Mel Tappan, who also authored the books Survival Guns and Tappan on Survival. The newsletter included columns from Tappan himself as well as notable survivalists such as Jeff Cooper, Al J Venter, Bruce D. Clayton, Nancy Mack Tappan, J.B. Wood (author of several gunsmithing books), Karl Hess, Janet Groene (travel author), Dean Ing, Reginald Bretnor, and C.G. Cobb (author of Bad Times Primer). The majority of the newsletter revolved around selecting, constructing, and logistically equipping survival retreats.[9] Following Tappan's death in 1980, Karl Hess took over publishing the newsletter, eventually renaming it Survival Tomorrow.
"Mini survival kits" or "Altoids tin" survival kits are small kits that contain a few basic survival tools. These kits often include a small compass, waterproof matches, minimum fishing tackle, large plastic bag, small candle, jigsaw blade, craft knife or scalpel blade, and/or a safety pin/s. Pre-packaged survival kits may also include instructions in survival techniques, including fire-starting or first aid methods. In addition, parachute cord can be wrapped around the tin. The parachute cord can be used for setting up an emergency shelter or snaring small animals. They are designed to fit within a container roughly the size of a mint tin.

The kits provided for Soviet and Russian Cosmonauts are optimised for survival in the temperate and sub-arctic mountains, forests and grasslands in the east of the country. Soyuz spacecraft kits include "food rations, water bottles, warm clothing, rope for making a shelter using the capsule’s parachute, fish hooks and miscellaneous other survival gear". The TP-82 Cosmonaut survival pistol, was provided to defend against predators such as wolves or bears. It was able to fire conventional bullets, shotgun cartridges and flares; the folding stock could be used as a shovel and it also had a fold-out machete.[8]

Survival kits, in a variety of sizes, contain supplies and tools to provide a survivor with basic shelter against the elements, help him or her to keep warm, meet basic health and first aid needs, provide food and water, signal to rescuers, and assist in finding the way back to help. Supplies in a survival kit normally contain a knife (often a Swiss army knife or a multi-tool), matches, tinder, first aid kit, bandana, fish hooks, sewing kit, and a flashlight.

Some evangelical Christians hold to an interpretation of Bible prophecy known as the post-tribulation rapture, in which the world will have to go through a seven-year period of war and global dictatorship known as the "Great Tribulation". Jim McKeever helped popularize survival preparations among this branch of evangelical Christians with his 1978 book Christians Will Go Through the Tribulation, and How To Prepare For It.
Firearms instructor and survivalist Colonel Jeff Cooper wrote on hardening retreats against small arms fire. In an article titled "Notes on Tactical Residential Architecture" in Issue #30 of P.S. Letter (April 1982), Cooper suggested using the "Vauban Principle", whereby projecting bastion corners would prevent miscreants from being able to approach a retreat's exterior walls in any blind spots. Corners with this simplified implementation of a Vauban Star are now called "Cooper Corners" by James Wesley Rawles, in honor of Jeff Cooper.[6] Depending on the size of the group needing shelter, design elements of traditional European castle architecture, as well as Chinese Fujian Tulou and Mexican walled courtyard houses, have been suggested for survival retreats.
Lightweight survival kits are generally seen as a backup means of survival; however, these can kits can be extensive, and have come to include tools that are generally found in larger kits as survival technology advances. Some examples of these tools are high power flashlights, rapid use saws, signal devices such as mini signal mirrors, and water purification methods.

Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
